You have collected the following data on output and total variable costs:

Q	TVC ($)
10	6,780
20	11,840
30	16,260
40	21,120
50	27,500
60	36,480
70	49,140
80	66,560
90	89,820
100	120,000

a. Identify the range of output exhibiting increasing returns (increasing MP), and the range exhibiting diminishing returns (decreasing MP).

b. Current fixed costs for the company equal $9,300. Draw two graphs, both with Q on the horizontal axis: one graph shows TVC and TC, and the other shows AVC, ATC, and MC.

c. Suppose that the government imposes a $3,600 property tax hike on all businesses; how will that affect your two graphs; i.e., which cost curves will be affected and how?

d. Suppose instead that the government considers your production process to be polluting, and imposes a $94 tax per unit produced (replacing the property tax in the previous question). How does this tax increase compare to the property tax increase, in terms of the effect on your companys cost curves?

e. Your boss says either of these taxes is going to force us to change our production levels. Given what you know about optimization analysis, how would you respond?
